湛江七种红树植物造林试验

Experiment on Afforestation of Seven Mangrove Species in Zhanjiang

通过树种选择和不同潮水位适应性试验,在湛江由于围海造塘等致使海岸线后移、水位普遍高、用红树林种子胚轴无法造林成活的沿海滩涂地造林,在苗木高度为50~60cm时,树种最好为白骨壤(Avicennia marina(Forsk.)Vierh.),其次为无瓣海桑(Sonneratia apetala Buch.-Ham.)和拉关木(Laguncularia racemosa(L.)Gaertn.F.)。无瓣海桑、拉关木、白骨壤可在1.85~2.45m(黄海高程,下同)滩涂地造林,红海榄(Rhizophora stylosa Griff.)可在2.15~2.45m滩涂地造林,秋茄(Kandelia obovata)、木榄(Bruguiera gymnorhiza(L.)Lam.)和桐花树(Aegiceras corniculatum(Linn.)Blanco)均不可在小于2.45m滩涂地造林。

Through tree species selection tests and adaptability tests of different tidal level,the afforestation was carrying out in coastal tidal flat of Zhanjiang where the shoreline moves backward,the water level is generally high,and the hypocotyls of mangrove seed cannot be used for afforestation due to pond reclamation.When the seedling height is 50~60cm,the best tree species is Avicennia marina(Avicennia marina(Forsk.).Vierh.)which was followed by S.apetala(Sonneratia apetala Buch.-Ham..)and L.racemosa(Laguncularia racemosa(L.)Gaertn.F.).S.apetala,L.racemosa and Avicenniamarina can be afforested on 1.85~2.45 meters(Yellow Sea Datum,the same below)beach,R.stylosa(Rhizophora stylosa Griff.)can be afforested on 2.15~2.45 meters beach,K.candel(Kandelia candel(L.)Druce),B.gym-noihiza(Bruguiera gymnorhiza(L.)Lam.)and Aegiceras corniculatum(Aegiceras corniculatum(Linn.)Blanco)can not be afforested on the beach less than 2.45 meters.
